Depends upon how much it is. The longer you wait, the less you get curation.

Personally. I would do it ASAP and then stack until the 15th.

Thinking through this. However, I have reached 30% o my target amount.Earned some and bought some.

That is good. The more you have powered up, the more you will earn with curation. That is how it helps to build.

Thank you. I will powerup in August 1 and stack more for August 15

If you think that best.

Wait till LPUD. That's the ideal day for it. And you can use it and create content.
